Heading F3A. Apparatus for assembling electric detonators as in Specification 716,357 comprises a reciprocating table 4 around the periphery of which are holders 5 arranged in groups which can be presented intermittently to a device 160. Each holder 5 can be tilted through 90 degrees to form a vertical plug receiving position to a horizontal position. Plugs (101), Fig. 11 (not shown) complete with electric fuzeheads (102) are taken by hand from supply means (not shown) at 106 and placed in the upright holders 5. The holders 5 then move into alignment with device 160, which comprises a group of detecting units. When a spring-stressed finger 90 in the unit contacts a plug in a holder 5, a microswitch 87 is actuated and energizes an electromagnet 30 which controls the supply of detonator-charge carrying sleeves from a magazine 13 to grooves in a plate 14, whence the sleeves 104 are blown into conveyer tubes 15 and thence into a chamber 51. Rods 9 push the sleeves into crimping means 54. After presentation to the device 160, the plug holders move around the table 4 to the next station which is adjacent a holder 7. A cam (62), Fig. 8a (not shown) mounted on table 4 tilts each holder through 90 degrees as it moves to this station A so that each holder is horizontal above a conveyer 105 and aligned with a sleeve 104 in the holder 7. Fingers (76) (Fig. 8a) then thrust the plugs in the holders 5 into the sleeves 104 where they are secured when pressure is applied to collets (53) by rings (55) on oscillation of the block (54). The assembled detonators are then carried away by the belt 105. The electromagnet 30 moves a lever 31, so freeing a pin 34 on clutch member 33. Pin 34 then engages a groove in a rotating shaft 32 to engage the clutch. A cam 35 on member 33 depresses a rod 36 to open a valve 38 and admit compressed air to a conduit 23. On the completion of one revolution the circuit is broken, pin 34 re-engages lever 31 and the valve 38 closes.

Abstract: 638,443. Television. CINEMA-TELEVISION, Ltd., and JESTY, L. C. Oct. 31, 1947, No. 29108. [Class 40 (iii)] In an arrangement for recording television pictures, reproduced by interlaced scanning, on intermittently moving kinematographic film some only or parts of some, or parts of all field traverses are recorded and the resulting gaps filled in by electrical or optical means. In one embodiment employing a standard intermittent motion camera with a 50 per cent pull-through time and in which the picture to be recorded is reproduced by a double interlaced scan on the screen of a picture reproducing tube the camera shutter and pullthrough mechanism are arranged so that alternate field scans only are recorded and the scanning spot dimension is increased in a direction perpendicular to the direction of line scanning so that the lines of the recorded single field are of double thickness. In a further embodiment employing a camera with a pull-through time of 12¢ per cent the whole of one field and part of the next (interlaced) field is recorded, the lines of double thickness being arranged to appear at the top and bottom of the recorded picture with a normal double interlaced picture at the centre. The increase in size of the scanning spot which is necessary to trace the double-width lines may be effected by employing electron-optical components in the gun of the picture-reproducing tube or by applying an additional, high-frequency, scanning component to the scanning beam in a directional perpendicular to the line scanning direction. Alternatively, a single line scan on the picture reproducing tube may be used and cylindrical lens means employed to widen the spot, the deflection in the frame direction being obtained by mechanical scanning means.

IPC: C08G64/20
Filed: 1965-07-09
Abstract: A continuous process for making polycarbonates comprises continously feeding a dihydric compound, phosgene, a chain-terminating agent and a catalyst to a reactor in which polycondensation is effected by the interfacial process and in which the aqueous and organic phases immediately on reaching the reactor are emulsified by intimate mixing, the emulsion containing the reaction products being withdrawn from the reactor.  Emulsification may be effected ultrasonically or by high speed stirrers.  Reaction may be effected in two consecutive reactors (which may be two compartments in a single casing) and the reactants may be fed only to the first reactor or to both. Alternatively, the catalyst and chain-terminating agent may be fed only to the second reactor or divided between both.  The reactants and solvent may be pre-cooled before admission to the reactor. In examples, the dihydric compound was bisphenol A, the chain-terminating agent was phenol, the catalyst was triethylamine and the organic solvent was methylene chloride.
